Abstract
A rolled film capacitor includes a first dielectric layer of high crystallinity polypropylene and a first metalized electrode stack adjacent to and contacting the first dielectric layer. The first metalized electrode stack includes a first substrate located between first and second metallic films. The capacitor also includes a second dielectric layer of high crystallinity polypropylene, and a second metalized electrode stack adjacent to and contacting the second dielectric layer, the second metalized electrode stack comprising a second substrate located between third and fourth metallic films.
